Peru's government has said it will appeal against a Chilean judge's decision not to extradite former Peruvian President Alberto Fujimori.

Mr Fujimori has been accused of human rights violations and corruption by Peru's prosecutors, but the judge said the evidence was not strong enough to warrant extradition.

Readers from Chile, Peru and Japan, where he also holds citizenship, emailed the BBC News website with mixed reactions to the decision.

REACTION FROM PERU

Send him back here to face the justice of a Peruvian judiciary. The constitution guarantees him a fair trial.David, Arequipa, Peru

It's inappropriate for the Chilean government to get involved with this, especially with something as serious as the extradition of an ex-president. Fujimori should be forced to return to Peru and face the charges against him. If he is not guilty as he claims then this will come to light in a court of law.Natalia Bogle, Lima, Peru

I am pleased at the ruling. So far there is no concrete proof that Mr Fujimori has done anything wrong.Tim Bayly, Lima Peru

Fujimori should not face extradition. Most Peruvians agree that he saved us from terrorism and an economic debacle

Lorena Murguia, Lima, Peru

I think this initial failure in the extradition process means a weakness in our government's handling of it. And what's worse, that may not be a coincidence, as in today's Peruvian politics Fujimori's influence can be clearly seen. Who will answer if this stops here and he gets away with it? Many would have to, but I am sure no one actually will.
Fernando Noriega, Lima, Peru

Fujimori should not face extradition. Most Peruvians agree that he saved us from terrorism and an economic debacle. If this is a case of short-term memory loss then, why wasn't [current] President Garcia prosecuted? He severely damaged our country with his economic policies during his first government.
Lorena Murguia, Lima, Peru

Fujimori conjures mixed feelings for the people of Peru because of his war against the guerrillas and stable economy. The current president, Garcia, is also viewed by many as corrupt, but is not the media darling that Fujimori was before his removal. When will Peru get a president that is not corrupt? We need to punish all corruption before we can move forward. Domingo, Cusco, Peru

Peruvian society, even now, is divided between those who accuse Fujimori of being the worst threat to democracy in history and those who still praise him for the "resuscitation" of the country's economy. However, many Peruvians still argue that extradition to Peru was something not only legally plausible but also, given the gross human rights violations our ex-president has been accused of, it was something morally mandatory and a responsibility for the judicial systems of both Japan (who protected him by saying that they do not extradite Japanese citizens) and Chile.Luis Tsukayama, Lima, Peru

Astonishing! I haven't read the considerations the Chilean Judge used to issue its verdict, but I'm very disappointed. I thought Chilean justice would deliver, for someone that took advantage of his position, and did much damage to our integrity.Paolo Pollari, Lima, Peru

This case is too complicated to look at it in black and white. The Peruvian government wants justice as well as the Chilean judiciary but Peru's ruling party does not like the idea of having Fujimori in Peru raising his political profile and causing political unrest. On the other hand, both countries disagree on their maritime boundaries and they are bringing the case to the International Court of Justice. Perhaps, by opposing the deportation process, Chile is taking this opportunity to cooperate during a difficult political time with Peru. Fujimori is a disgrace for Peru and the region.
Marcelo, Lima, Peru

Mr Fujimori has much to answer before a jury, whether in Lima, Santiago or The Hague. Even though many prominent political figures or business people may fall in the process, there are a number of issues which Peruvians need clarified. Let us not forget the time lost regarding former Chilean president Mr Pinochet, who died, leaving uncertainty forever. Luismiguel Espejo, Lima, Peru

Fujimori did a lot of good for Peru and I don't think it is in our interest to have him humiliated in the courts. Let him live peacefully in Peru. For a corrupt continent, he was much less corrupt than the vast majority of South American leaders, and helped to solve some bad problems. We should keep things within context, and recognise the good he did, which outweighs the bad.John Galley, Lima, Peru

REACTION FROM CHILE

The whole Fujimori business in Chile has been a farce. Firstly the immigration detectives allowed him to enter Chile using a passport in his name. Had nobody in immigration ever heard of him? He was the president of a neighbouring country and had left in a huge scandal! Then Chile seemed to think that the international community and Interpol were wrong and started a two-year trial. Chile's reaction was very different when Pinochet was held in London and they wanted him returned!
Jeff Jagger, Arica, Chile

I don't believe extraditing Mr Fujimori to Peru would serve much purpose. It would cause internal tensions and further polarise Peruvian opinion. Christopher Beggs, Santiago Chile

I'm ashamed of being Chilean. We are unable to uphold justice

Carvajal Zunilda, Santiago, Chile

Mr Fujimori's case is very similar to Pinochet's case in London, where Jack Straw let him go just like this Chilean judge did with Fujimori. I remember I was very disappointed that a great country like England did nothing to uphold justice in that particular case. I think that the people of Peru must feel the same about our country.Oscar Novoa, Valparaiso, Chile

Nobody here can believe this ruling. Weeks ago the prosecutor of the Supreme Court recommended the extradition of Fujimori for crimes against humanity and corruption. Now the Supreme Court, in plenary session, will review the resolution and they'll take the final decision.Roberto Arteaga, Santiago, Chile

I do not agree with the resolution of the Chilean judge. Fujimori must be judged in his country, Peru, and answer before its own courts. Felipe Miranda, Chile

I think that Chilean justice acts regardless of pressure. We must wait for the outcome of the appeal. Mauricio Dasencich, Santiago, Chile

I'm ashamed of being Chilean. We are unable to uphold justice. The Chilean judicial system doesn't make sense anymore after this unfair ruling.Carvajal Zunilda, Santiago, Chile

Unbelievable. This man should stand trial in his home country. Denying extradition sets a dreadful precedent in the fight against corruption and state crimes in South America.Javier Diaz, Santiago, Chile

REACTION FROM JAPAN

Mr Fujimori belongs to a group of the most cynical public servants. Japan should not allow him to run away from his crimes.Jose Valdivieso, Japan

Japan does not permit dual nationality, and yet Fujimori can run for election here

Tony Kehoe, Tokyo, Japan

For people like me of Japanese origin with immigrant roots in Latin America, this has been a puzzling series of double standards. Fujimori, a Peruvian, has been granted asylum in a country that strictly forbids dual citizenship. We of Japanese descent do not even have the right to remain in this country because we are citizens of Latin American states and it is extremely hard even to acquire a visa or long term residency permit. Now an opposition party has recruited Fujimori to run in elections here. This is a de facto acceptance of his dual citizenship. Either halt this manipulation or start giving better immigration rights and laws to Japanese and foreign immigrants!Yutaka, Japan

Interesting that Japan does not permit dual nationality, and yet Fujimori can run for election here whereas those like me don't even get a vote. Tony Kehoe, Tokyo, Japan

This whole issue has implications for Japanese nationality laws. Japan does not allow dual nationality and bicultural children must choose their nationality at age 22. Peruvian law does not allow a foreigner to be president and Fujimori clearly is a Peruvian national, having been president for 10 years. When he fled to Japan, the Japanese government refused to extradite since they claimed he is a Japanese national based on a family registration filed in Japan by his Japanese father, thereby acknowledging the right to dual citizenship. Now, he is talking of standing for Japan's Senate - a position that can only be held by a Japanese national. Although not yet tested in a court of law, this sets an important precedent that may see Japan forced to change its stance on dual nationality. Robert Hancock, Tokyo, Japan
